SVBONY SV220 Telescope Filter, SII & OIII 7nm Dual-Band 2" Nebula Filter, High Transmission Cut-Off Depth OD5, Enhancing Imaging Contrast, Reduce Light Pollution for Astrophotography
SVBONY SV220 Telescope Filter, SII & OIII 7nm Dual-Band 2" Nebula Filter, High Transmission Cut-Off Depth OD5, Enhancing Imaging Contrast, Reduce Light Pollution for Astrophotography
- SV220 2'' Dual Narrow bandwidth SII/O-III 7nm narrowband filter properly designed for astrophotography both in light polluted
- Allows for imaging in bright man-made light pollution and moonlit conditions; Useful for imaging emission nebulae; planetary nebulae and supernova remnants
- Designed to sharply cut off the inference of artificial light from sodium vapor or mercury vapor street lights and other unwanted disturbance like sky glow
- Note Recommended for optical systems from > f/4
